[frog210]

Well this time im working on my heater everything seem good untill i check under the dash and saw a bunch vacuum lines missing, so i decided to take a picture it might help some people or yall can help me
it turns on, if i switch the the on switch i hear the blower turn on, but i see that i have a few ports that dont have any vacuum line where they should be some
i found only 2 vacuum lines
one black and grey
one black and red, goes into a T fitting with 2 other black and red lines
i know i my vacuum controller is missing from behind the a/c control switch
i dont know maybe i can just route all the vacuum lines, line by line, or maybe one of yall can show me a only place o get thank you
maybe a expert like motornut, 85gmcguy can point out any flaws

okay so the door aint suppose to close all the way as seen in your second picture right?
also if you have a chance can you tell me what color the vacuum line goes to the vacuum advance by your gas pedal
also what color the vacuum line is that goes to passenger kick panel vacuum advance is ?
I also moved the doors and tested the vacuum advances and heard air coming when i move the door,
also this is a 74 c10

also just wanted to make sure my water lines where put on right
i have a red hose that goes from top of the radiator by the cap to the top of the 2 outlets coming out of the firewall
I have a black hose that goes from the intake to the bottom outlet that comes out of the fire wall
i hope i dont confuse yall lol

-Yes it closes the vents off,aims to the def/floor
also if you have a chance can you tell me what color the vacuum line goes to the vacuum advance by your gas pedal
-Sorry it's not close to me,it's off the road now
also what color the vacuum line is that goes to passenger kick panel vacuum advance is ?
I also moved the doors and tested the vacuum advances and heard air coming when i move the door,
-Sounds promising,once you feed the main,check on each setting should help sort it
keep in mind when you need vac to the pass side vent,to close off outside air
maybe snag a pic of the floor/def valve inside the box,does it have the three holes to choose air flow like i remember?depending on the setting I think it might frustrate some people,thinking something is wrong...
-my 79 is like that
-my 78 intake to top,bottom to pump

[frog210]

my top hose red goes to the radiator by the top to put coolant in
and my bottom one goes to the intake on the engine
ive had my truck on and it never seems to get hot, like blow hot air nor do the lines seem to get hot
you might have to zoom in to see the lines

[frog210]

I went to the junkyard went in and was told i only have 15 minutes till they close, i ran in and found this truck pulled the rubber from the back and foundthe plug i need
heres a pic
also i noticed the plug i got
only had 5 lines the other four ports arent used, it looks factory
i got to try and see what the lines go hooked up to know i know some
but still needs some advice
